Hybrid 100V's unique small grain, part Spherical, part Extruded shape benefits the handloader in two ways- the powder flows accurately and easily through a measure, and charge weights are consistent for ideal load density. It is ideal for use in calibers that fit H4350, delivering velocities not seen before in a variety of popular cartridges, such as 3,310 fps for a 150-grain bullet in the 300 Weatherby Magnum.
